Flame retardant for epoxy resin products
The majority of epoxy resin products with flame retardant containing halogen, Yantai Dalian in hair produced during the combustion of toxic gases, so in recent years the epoxy resin products used by non halogenated flame retardant is more and more urgent.
Some of the plastic products in developed countries have begun to prohibit the use of halogen flame retardants, and the EU's "two directives" on environmental protection have made clear restrictions.
Epoxy resin development is very rapid, Chinese has become a major market of epoxy products. Flame retardant epoxy resin products used can cover and contain everything. Application of epoxy resin can be divided into the following parts.
(1) the automobile industry is one of the four pillar industries in China, and the demand for automobiles is increasing. The electrophoresis paint required epoxy resin and epoxy curing agent, and the paint needs epoxy as well.
(2) electric power industry: China's power industry is large and is in a fast developing stage, and its epoxy is expanding at an annual rate of 60%. In this field, epoxy products are needed for power generation, power transmission and transmission to power supply, such as insulation materials, dry type transformers, switches, transformers, water conservancy and Hydropower projects. Cut an irreplaceable role in the construction and operation of hydroelectric power station in epoxy resin and curing agent of epoxy resin.
(3) ships, marine industry: Chinese maritime power, shipbuilding country, twenty-first Century is the century of the ocean. Ships, wharf facilities, offshore buildings, drilling platforms, oil pipelines, marine aquaculture facilities and so on, need a large number of epoxy coatings (anti-corrosion, marine biological pollution).
(4): China electronics industry is one of the four pillar industries, the rapid development of. Epoxy resin and epoxy curing agent in the role of the electronic industry is very important, epoxy resin adhesive industry has become a very large industrial chain.
(5) container industry: the rapid development of China's container industry, has become the world's major container production base (accounting for 10% to 15% of the world's total). Container coatings and special curing agents for container coatings drive the development of epoxy resin and epoxy curing agent industry.
(6) food cans industry: with the improvement of living standards, canned food, food storage containers manufacturing industry continues to develop rapidly, cans paint needs more and more epoxy resin.
(7) on the epoxy resin varieties, promising epoxy powder coatings, waterborne epoxy coatings. Both of them are the mainstream of epoxy coatings. China is the world's fourth largest powder coatings producer, is Asia's largest producer of powder coatings. In China, powder coatings and waterborne coatings have been identified as priority varieties in the future, and waterborne epoxy coatings play an important role in the waterborne coatings industry.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
CAS No.:13674-87-8
HS: 29199000
Tax Rate (%): 9%
Tris (1,3-Dichloro-2-Propyl) Phosphate (TDCPP) Raw Materials: Phosphorus Oxychloride, Epichlorohydrin
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
Epoxy resin and epoxy resin curing agent affects the development of the industry. As industrial control indexes of resin are as follows:
Epoxy value. Epoxy value is the most important index to identify the properties of epoxy resin. The type of epoxy resin is different according to the different epoxy value. The epoxy value of epoxy is contained in each 100g resin material quantity. The reciprocal of the epoxy value multiplied by 100 is called epoxy equivalent. Epoxy equivalent means: 1mol containing epoxy epoxy resin grams.
Inorganic chloride content. The chloride ion in the resin can be combined with amine curing agent to affect the curing of the resin, and also affect the electrical properties of the cured resin. Therefore, the chlorine content is also an important index of epoxy resin.
Content of organic chlorine. The content of organic chlorine in the resin marks the content of the part of chlorine alcohol which has no closed loop reaction in the molecule, and its content should be reduced as much as possible, otherwise it will affect the curing of the resin and the property of the curing agent.
Volatile matter.
Viscosity or softening point.
The waterborne epoxy resin curing agent commonly used emulsion method to prepare waterborne epoxy resin emulsion. The epoxy resin in this system is generally not emulsified in advance, and emulsified by waterborne epoxy curing agent before mixing. Therefore, the curing agent must be both a curing agent and an emulsifier.
According to the different preparation methods, there are four methods of waterborne epoxy resin: mechanical method, chemical modification method, reverse conversion method and curing agent emulsification method.
The mechanical method is direct emulsification method, colloid mill, ball mill, all available apparatus will advance into micron solid epoxy resin epoxy resin powder, then adding emulsifier aqueous solution, by mechanical stirring the particles dispersed in water; or the epoxy resin and the mixed emulsifier, heated to proper temperature, stirring in the fierce gradually add water emulsion formed.
The advantages of the preparation of waterborne epoxy resin emulsion by using mechanical method is a simple process, the required amount of emulsifier is less, but the emulsion of epoxy resin dispersed phase particle size larger, irregular shape and particle size distribution is wide, the emulsion stability deserves to have difference between the particles easily collision occurred while the phenomenon of condensation, and film properties the emulsion is poor.
